This study focuses on the elderly memo app “Remembering,” addressing memory decline and operational difficulties. It introduces a progressive interaction system with three core modules: Dynamic font adjustment, intelligent voice reminders, and family warning systems. Health monitoring and remote care functions are also integrated, creating a simple operation process. The research highlights four design dimensions for elderly-friendly products: Usability, security, emotionalization, and personalization. This innovation reduces the digital barrier and provides a model for smart elderly-friendly product development.
